I was partially wrong.  In HIVE-12366 Wei refactored this so that the heartbeats are sent
from the client rather than from the execution engine.  This JIRA has been committed to master
and branch-1, but after 1.2.  So Hive on Spark should work fine with transactional tables
in Hive 2.x.  In 1.2 and earlier it will not.
